Discussion article for the meetup : Washington DC: Robin Hanson visits to talk about giving

WHEN: 30 March 2014 03:00:00PM (-0400)

WHERE: National Portrait Gallery

Robin Hanson will be visiting to discuss the issues involved with giving now vs. giving later (for example, saving up as much money as you can and donating your estate to an effective charity when you die).

As usual, the conversation may drift to whatever folks are most interested in.

Meetup : Washington, DC: Goals

Discussion article for the meetup : Washington, DC: Goals

WHEN: 01 September 2013 10:45:39AM (-0400)

WHERE: National Portrait Gallery

We'll be meeting to talk about goals, both long-term and short-term. Do you have a Plan? Do you think you need one? What projects are you working on / do you want to start? I'd also like to start a regular system (used by the NY self-improvement group) where we talk about our goals for the next few weeks, and check in on them after that time has passed. I will also be bringing an array of toys (a PowerBall, a cylindrical sliding puzzle, and similar items). We'll be meeting in the courtyard adjoining the National Portrait Gallery, as usual.

Meetup : Washington DC meetup: Robin Hanson visits again

Discussion article for the meetup : Robin Hanson visits to talk about prediction markets

WHEN: 08 September 2013 03:00:00PM (-0400)

WHERE: National Portrait Gallery

(This meetup is being posted a few weeks before it will occur.)

Since we mostly talked about ems and AI last time he was here, Robin Hanson is visiting again, this time with more of a focus on economics and prediction markets. (Though as always, the discusssion will also be shaped by the interests of the participants.)

The meetup will be in the courtyard adjacent to the National Portrait Gallery, as usual.

[Link] You May Already Be Aware of Your Cognitive Biases

6 maia 21 February 2013 01:23PM

From the article:

Using an adaptation of the standard 'bat-and-ball' problem, the researchers explored this phenomenon. The typical 'bat-and-ball' problem is as follows: a bat and ball together cost $1.10. The bat costs $1 more than the ball. How much does the ball cost? The intuitive answer that immediately springs to mind is 10 cents. However, the correct response is 5 cents.

The authors developed a control version of this problem, without the relative statement that triggers the substitution of a hard question for an easier one: A magazine and a banana together cost $2.90. The magazine costs $2. How much does the banana cost?

A total of 248 French university students were asked to solve each version of the problem. Once they had written down their answers, they were asked to indicate how confident they were that their answer was correct.

Only 21 percent of the participants managed to solve the standard problem (bat/ball) correctly. In contrast, the control version (magazine/banana) was solved correctly by 98 percent of the participants. In addition, those who gave the wrong answer to the standard problem were much less confident of their answer to the standard problem than they were of their answer to the control version. In other words, they were not completely oblivious to the questionable nature of their wrong answer.

Meetup : Washington, DC Meetup with Special Guest

WHERE: National Portrait Gallery, Washington, DC

After some of the DC group attended a talk by Robin Hanson, I asked him to come visit a meetup! And even better, he agreed!

Those who didn't come to the talk can hear more about the idea of a future em economy, and what it would likely entail. (Or other ideas about what the future might hold?)

We may also discuss issues of interest to contemporary economics, including prediction markets.

[LINK] Learning without practice, through fMRI induction

2 maia 07 October 2012 03:15AM

http://www.nsf.gov/news/news_summ.jsp?cntn_id=122523&org=NSF&from=news
From the article:

New research published today in the journal Science suggests it may be possible to use brain technology to learn to play a piano, reduce mental stress or hit a curve ball with little or no conscious effort. It's the kind of thing seen in Hollywood's "Matrix" franchise.

Think of a person watching a computer screen and having his or her brain patterns modified to match those of a high-performing athlete or modified to recuperate from an accident or disease. Though preliminary, researchers say such possibilities may exist in the future.

Experiments conducted at Boston University (BU) and ATR Computational Neuroscience Laboratories in Kyoto, Japan, recently demonstrated that through a person's visual cortex, researchers could use decoded functional magnetic resonance imaging (fMRI) to induce brain activity patterns to match a previously known target state and thereby improve performance on visual tasks.

EDIT: To clarify, this is almost certainly over-hyped. However, it appears to at least be an instance of very interesting biofeedback.

[POLL RESULTS] LessWrong Members and their Local Communities

0 maia 21 May 2012 04:37PM

The results for these have been stable for a while now; I'm posting them a bit late. 95 people took the survey after I modified it to add two questions. For the public version, I removed the pre-change data (10 data points).

One text response included identifying information, which I removed in the public version of the data. If you participated and there is any information you provided that you would like removed from the public version, PLEASE tell me as soon as possible and I will remove it.

P.S. To the person who predicted an 80-90% significant difference between different parts of California: I predict with at least 90% confidence that there will be no significant difference, because of the wide spread of locations and smallish sample size of this survey.

(The original post about the survey.)

EDIT: After some comments that it was unethical for me to post the data (in particular the text), I removed public access from the link provided earlier. Given my precommitment to post the data, I assumed it was clear enough to respondents that it would be public. I'm not convinced that this has hurt anyone, but given that others seem to disagree, it seemed prudent to remove it. Please feel free to continue this discussion; I'm interested in your thoughts.

[POLL] Do You Feel Oppressed?

6 maia 03 May 2012 02:42AM

At Reason Rally a couple of months ago, we noticed that a lot of atheists there seemed to be there for mutual support - because their own communities rejected atheists, because they felt outnumbered and threatened by their peers; the rally was a way for them to feel part of an in-group. Reason Rally is definitely an event that selects for people who feel excluded by their communities most of the time. But there may be a different concentration of people who have had this sort of experience on LessWrong, and we wondered what that concentration was.

Hence, this survey: LessWrong Members and their Local Communities.

If I get a decent sample size, I will post the data for all to enjoy.

EDIT: I added two questions about current and previous religious views to the poll. If you took it before 11:30PM EST 5/2, I'd appreciate it very much if you would take the time to retake it. :)
